Experimental Analysis regarding SelfAssembled Debris on Profile Management inside the Fuyu Oilfield

Parasadoletus exsertus gen. and sp. nov. (Hemiptera Heteroptera Lygaeoidea Heterogastridae) is described from Mount Glorious, southeastern Queensland, Australia, based on specimens collected associated with a rainforest tree Argyrodendron actinophyllum (F. M. Bailey) Edlin (Malvaceae). The new genus is compared and its relationship with other known genera of the family Heterogastridae elucidated, also comments on host plant associations within this family are provided.The Brazilian genus Machima Brunner von Wattenwyl, 1878 includes three valid species M. paranensis Rehn, 1950 and M. scalprum Rehn, 1950 distributed on Southern and M. phyllacantha (Burmeister, 1838) from Northeastern Brazil. Herein we analyzed eleven male specimens of Machima from Parque Nacional de Itatiaia and propose a new species. Machima itatiaia sp. nov. is characterized by its main lobe of the cercus curving abruptly on apical two-thirds and accessory lobe as long as wide. The new species is the first record of the genus from Southeastern Brazil. Finally, we also present a key to species of Machima based on males.Pentamera fonsecae n. sp. is described from seven specimens as a new species of Thyonidae from the Pacific coast of Costa Rica. It is distinguished from its congeners by having tables with ladder-shaped spires in the body wall, and tube feet with curved support tables of variable height and tables as those found in the body wall slightly smaller than those from the body wall. This species is distributed in Guanacaste, Costa Rica, from 28.5 to 40 m on muddy bottoms.Didelphis aurita Wied-Neuwied, 1826 is a marsupial well adapted to anthropogenic activity and commonly found in urban areas of Brazil. Among the gastrointestinal parasites found in this opossum, protozoa of the genus Eimeria are frequently detected. This study investigated the biodiversity of Eimeria species infecting D. aurita in Southeastern Brazil, and provides morphological data on a newly discovered species of Eimeria. From January to June 2019, 43 D. aurita were captured, and their fecal samples were collected and evaluated by salt flotation; positive samples were allowed to sporulate in 2.5% potassium dichromate (K2Cr2O7), and detailed morphological measurements were performed to determine the species present. Thirty-two of forty-three (74.4%) opossums were infected with from one to five Eimeria spp. Four of the eimerians were described and named previously by others Eimeria auritanensis, Eimeria caluromydis, Eimeria gambai, and Eimeria philanderi. Additionally, sporulated oocysts of a species new to science were detected. Oocysts of this new Eimeria species are spheroidal to subspheroidal, 21.7 × 20.7 (20-23 × 19-23), length/width (L/W) ratio 1.05, with a highly refractile polar granule, but lacking a micropyle and oocyst residuum. Sporocysts are ovoidal, 10.6 × 8.0 (9-12 × 7-9), L/W ratio 1.3, with a small, Stieda body and a sporocyst residuum of diffuse granules. Of the infected opossums, 5/32 (16%) were infected with only one Eimeria sp., 6/32 (19%) with two, 15/32 (47%) with three, 5/32 (16%) with four and 1/32 (3%) with five Eimerians.Five new species of the leafhopper genus Limassolla Dlabola, Limassolla bicruralis, L. kunyica, L. uncata, L. nigropunctata, L. spinulata spp. nov., are described and illustrated and a key to separate males of those species is provided.The sharpshooter genus Balacha Melichar, 1926 has seven recognized species and is distributed in southern South America (Argentina, Brazil, Paraguay, and Uruguay). Here, two new Brazilian species of this genus are described and illustrated, one (B. ancora sp. nov.) from Serra do Caraça and Serra do Cipó (Minas Gerais State) and another (B. nigroflava sp. nov.) from Ponta Grossa (Paraná State) and Passo Fundo (Rio Grande do Sul State). Based on 67 morphological characters, we carried out a parsimony analysis to estimate the phylogenetic position of the two new species. Using implied weighting in TNT, a single topology within Balacha was obtained with k values that varied from 1.599 to 7.412. In this topology, the two new taxa appeared within the clade of black Balacha species. A biogeographical analysis (S-DIVA) suggested that the ancestral area of distribution of Balacha was the Atlantic Forest domain. Balacha species were so far known to have only Eryngium (Apiaceae) species as host plants. Here we report a new host plant for the genus B. ancora sp. Selleck LXS-196 nov. specimens were collected on Actinocephalus polyanthus (Eriocaulaceae). Balacha similis and B. rubripennis are newly recorded from Argentina and specimens of the latter have a very distinct color pattern from the typical Brazilian specimens. Finally, a key to species and maps showing the known distribution of the genus are given (several state records of species are also provided).Five species of decapod crustaceans, including Calliax nishiki sp. nov. (Axiidea, Eucalliacidae) and Carcinoplax longimana (de Haan), are described from the upper part of the Moeshima Silt Bed (latest Pleistocene to Holocene ca 13,000 to 8,000 cal BP). Ten decapods, including Laticallichirus grandis (Karasawa Goda) and Ebalia tuberculosa (A. Milne-Edwards) are described from the Moeshima Shell Bed (Holocene ca 8,000 to 2,000 cal BP). Calliax nishiki is abundant and Carcinoplax longimana is common in the decapod assemblage of Moeshima Silt Bed. The new species of Calliax seems to have dispersed around the deep marine setting with a reducing environment. The decapod assemblage of the Moeshima Shell Bed is characterized by a predominance of L. grandis. The present record suggests that L. grandis is abundant under sandy and gravelly bottoms mixed with shells of the lower sublittoral to subtidal zones during the Quaternary.A new species of gecko of the genus Hemidactylus (Squamata Gekkonidae) is described from São Nicolau Island, Cabo Verde Archipelago, and the Sal and Boavista island populations of Hemidactylus boavistensis (i.e., Hemidactylus boavistensis boavistensis comb. nov. and Hemidactylus boavistensis chevalieri comb. nov.) are recognized as subspecies. Hemidactylus nicolauensis sp. nov. is genetically distinct from H. bouvieri, to which it has previously been referred, and from all other closely related endemic Hemidactylus from Cabo Verde Islands in mitochondrial (12S cyt b) and nuclear (RAG2, MC1R) markers. It is characterized morphologically by its distinct colouration and a diagnostically different arrangement of digital lamellae. With the description of this new species, São Nicolau is now known to harbour three single-island endemic gecko species, and the documented reptile diversity in Cabo Verde is raised to 23 endemic species. As a result of our taxonomic changes, existing conservation regulations should be updated and the conservation status of these taxa should be re-evaluated.
